What causes lung cancer?

The incidence of lung cancer in China is increasing, and smoking is one of the main causes. So what are the other causes of lung cancer ? The following is a detailed answer from relevant experts.

(1) Smoking: It is now generally recognized that smoking is an important risk factor for lung cancer. Tobacco leaves and smoke contain a variety of ulcer-causing and cancer-promoting agents such as tar and benzophenone. It is estimated that about 85% of lung cancer is related to smoking, and the risk of lung cancer in smokers is 12-22 times higher than that of non-smokers. This is the cause of lung cancer.

(2) Air pollution: With the progress of society and the development of industry, the production and use of many industrial raw materials and products containing carcinogens have increased, which not only increases the number of workers directly exposed to lung cancer, but also aggravates the degree of air pollution caused by carcinogens. The exhaust gas discharged by cars, asphalt used in road and house construction, etc. all contain carcinogens, making air pollution increasingly serious. The incidence of lung cancer in industrially developed countries is higher than that in industrially backward countries, higher in cities than in rural areas, higher in large cities than in medium and small cities, and higher in urban areas than in suburbs. This may be related to the fact that air pollution is more serious in cities.

(3) Home environment: The decoration materials of the house and the fumes produced when cooking contain a lot of ulcer-causing substances. Passive smoking caused by family members smoking can also pollute the home environment. The incidence of lung cancer in women may be related to long-term inhalation of cooking fumes.

(4) Occupational carcinogens: Occupational carcinogens include organic arsenic compounds, asbestos, coal, smoke, tar, asphalt, smoke, mustard, dichloromethyl ether, vinyl chloride, nickel smelting, chromium, etc. Those who are exposed to occupational carcinogens for a long time at work have a significantly increased risk of developing lung cancer.

The above is an introduction to the causes of lung cancer. I believe everyone should have a certain understanding of lung cancer. If you want to know more about lung cancer, please consult online experts.
